Specification of Letters Patent.

Patented Oct. 29, 1918.

Application filed May 11, 1918. Serial No. 233,941.

To all whom it may concern Be it known that 1, FRANK J. Bunions, a citizen of the United States, residing at biohcnectady, in the county of Schenectady and; State of New York, have invented certainnew and usefullmprovements in Air- .Valves, of which the following is a specification.

In the operation of internal combustion engines, of the type utilizing liquid fuel, it has been discovered that a greater mileage may be obtained from a given amount of fuel by the admission of air into the mix ture at a point between the carburetor and the intake of the engine. This has been attributed to a more thorough vaporization of the fuel and the combining with the mixture of air for tempering the same with the result that a less amount of fuel is required for a given amount of mixture.

The purpose of the present invention is to provide a valve of unique structure whereby air in regulated quantity may be supplied to the mixture, such valve being of a construction to be readily applied to any type or make of internal combustion engine.

A further purpose of the invention is the provision of a valve which may be readily applied to or disconnected from the engine and which embodies a needle valve adapted to operate by a reciprocatory movement only, thereby assuring a firm seating of the needle to prevent the seat and the end of the valve from becoming unnecessarily worn.

The drawing illustrates a preferred embodiment of the invention. However, it is to be understood that in adapting the same to meet different conditions, various changes in the form, proportion, and minor details of construction may be resorted to without departing from the nature of the invention as claimed hereinafter.

In the drawing 1-- Figure 1 is a central longitudinal section of an air valve embodying the invention,

Fig. 2 is a transverse section on the line 22 of Fig. 1, and

Fig. 3 is a horizontal section on the line 3-3 of Fig. 1 looking in the direction of the arrows.

Corresponding and to in the following descri in the several views of t reference characters.

The valve comprises a casing 1 which as indi ated is of tubular form and open at both like parts are referred tion and indicated e drawing by like ends and having the end portions reduced and exteriorly threaded. A hollow extension 2 is provided at one end of the casing l and is closed at its outer end, such exten sion being of circular form and constituting a coupling element. A cap 3 closes the end of the casing 1 adjacent the lateral coupling extension 2 and is provided centrally with an opening 4 for the ingress of air. A chamber 5 is mounted upon the opposite end of the casing 1 and is retained in place thereon by means of a cap 6, such chamber being clamped between the inner end of the cap 6 and the shoulder formed at the inner end of the ex ternally threaded reduced end portion of the casing. A partition 7 is disposed within the casing 1 adjacent the lateral coupling extension 2 and is centrally apertured.

A needle valve 8 is disposed within the casing 1 and is mounted in the partition 7 and the cap 6. One end of the needle valve closes the opening i and its opposite end terminates within the chamber 5 and is formed with a depression 9. The valve is provided with a collar 10 which constitutes alstop for one end of a spring 11, the opposite end of such spring obtaining a bearing against the partition 7. The spring 1, is of helical form and expansible and constructcd of wire of small gage. The purpose of the spring 11 is to normally unseat the valve thereby permitting air to enter the opening 1 for a purpose and in a manner presently to be explained. A rod 12 is mounted in the outer end of the chamber 5 and its inner end 13 is made rounding so as to fit the depression 9 in the end of the valve 8. The rod 12 constitutes operating means for the valve and extends to a convenient point of operation.

A coupling is provided as means for attaching the valve to the manifold or other part of the engine to which the valve is adapted to be applied. This coupling cornprises a. split band 14 and a nozzle 15, the latter having an end portion reduced and externally threaded so as to make screw threaded connection with an opening formed in the manifold or other part adapted to receive the coupling. The split band 14 has the separated portions connected by means of a bolt 16 or like fastening Wherebv provision is had for tightening or loosening the split band as required. The nozzle 15 is provided with a central opening 17 which is adapted to register with an opening 18 formed in the side of the lateral coupling extension 2.

ln practice the manifold 01 other part of the engine to which the valve is to be ap plied is formed with a threaded opening to receive the threaded end of the nipple 15, and :1 Her the coupling, comprising the parts ll and l5, hm; been placed in position the taming l or l ()(l of the valve is fitted to the coupling by having" the lateral eXleir sion 2 ineerted in the split band 14., care being exercised to have the opening 18 reg ister with the opening 17 after which the bolt 16 is tightened so as to clamp the band ll about the lateral extension 2, thereby holding the val vc body or easing l in the re quired position againet possible movement. ()utwari'l movement of the rod 12 permits unseating ot' the valve 8 so that air may he passed through the opening -linto the ca ingl. thence through the hollow UXl'GIIRl U 2. and openinga 1i and 1 lltln thrmani told. (not shown) or other part, so as to nipply an 'dChlltlUllt'tl amount of air to the gawon mixture whereby the latter modi lied to (-iuch an extent 51$ to malnit possible to operate the engine with a less amount" of fuel with the result that a material saving results and the carbonizing' of the engine minimized.

The foregoing description and the drawing have reference to What may be considercd the preferred, or approved, form of my invention. It is to be understood that I may make such changes in the construction and arrangement and combination of Copies of this patent may be obtained for five cents each, by addressing the parts, materials, dimensions, et cetera, as may prove expedient and fall Within the scope of the appended claims.

l la vi ng thus fully described my invention, What I claim as new and desire to secure by Letters Patent is:

1. An air valve of the character specified, comprising a tubular body having a trans-- terse partition near one end and a lateral coupling extension between the partition and the adjacent end, caps closing the ends ol the body, the rap adjacent the coupling eXtens'ion having an opening, a needle valve slidable in the cap adjacent the coupling extension, a spring normally tending to hold. the valve unseated, a chamber at the end of the body remote from the coupling eX- teneion, and a rod mounted in the chamber and in contact with the valve for cflectine' seating thereof.

2. An air valve comprising a tubular hodyq cape threaded on the ends of said body. a valve slidahlv mounted Within the body, a sprin, on the valve and normally lending to hold the same unseated, a chain her held. on the valve body by means of one of said caps, and an operating rod mounted in the chamber and in contact with the valve for seating the the spring cooperating therewith.

In testimony whereof I afiix my signature in presence of two Witnesses.
